THERAPEUTIC OSCILLATOR.

Application filed January This invention relates to electrical therapeutic devices or apparatus used in the treatment of diseases in accordance with the Abrams and similar methods, and has for its object the provision of a novel oscillator embodying a three element vacuum tube for generating high frequency oscillations which. are caused to pass through the body of the patient in accordance I with the treating method.

An important and most specific object is the provision of an oscillator embodying a three element vacuum tube of the power type which has its filament energized by current supplied thereto by a. step-up transformer energized by an ordinary lighting circuit or current, the tube further having its plate electrode supplied with a high voltage current likewise derived from the transformer.

An additional object is the provision of an apparatus of this character which will be simple and inexpensive in its arrangement, positive in action, efiicient in service, and a general improvement in the art.

With the above and other'objects and advantagesin view, the invention consists in the details of construction, to be hereinafter more fully described and claimed, and illustrated in the accompanying drawing, which shows a diagram of the entire apparatus.

Referring more particularly to the drawings, the numeral 10 designates an ordinary step-up transformer having a primary coil 11 energized by connection with an ordinary hundred and ten or two hundred and twenty volt current line such as is used in private homes or in other places for electric lighting. The leads of this line are indicated by the numeral 12. The transformer has two secondary coils 13 and 14, the former of which is connected with the terminals of the filament 15 of a power vacuum tube 16 of the threeelectrode type. This tube embodies the usual plate electrode 17 which is connected by a wire or other conductor 18 with one terminal of the coil 14. Interposed between the lead from the other terminal ofthe coil 14, which lead is designated by the numeral 19, and the lead 20 from the grid element 21 of the tube, is a suit-able control inductance 22 having an output terminal 23 adapted for connection with'the patient in some suitable manner.

' The rheostat 22 includes an adjustable contact arm 24 connected with one of the leads 28, 1925. Serial No. 5,299.

of the filament 15.1 It should'best-ated in passing that the transformer disclosed is one of the step-up types'and may have a voltage arranging from three hundred to two thousand, depending on the requirement of the power tube used.

The theory of the oscillator isas follows: The tube generates high frequency currents which are somewhat similar in their nature and effect to the radio activity generated by the human body or caused by the existence of disease therein. The oscillator forming the subject matter of our invention, is in phase with the disease frequency and consequently this destroys the radio activity of tie disease and eventually eradicates the disease itself. it will be observed that there in only one output lead 28 shown connected with the grid and the rheostat and it is obvious that there must be another lead provided somewhere in order that the circuit may be completed through the body. For this reason it is obvious that the patient must stand upon some suitable conductor properly connected in the circuit in order to make it complete.

While we have shown and described the ,m'et'erred embodiment of the invention, it

should be understood that we reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claim.

Having thus described the invention, we claim:

In an apparatus of the character described, a transformer having a primary coil adapted to be energized by an alternatingcurrent of a voltage commonly usedin connection with house lighting systems, the transformer having two secondary coils, a three element vacuum tube including a filament having its terminals connected with one of said secondary coils, a plate having connection with one terminal of the other secondary coil, and an inductance located in series bet-ween the remaining terminal of the second named secondary coil and thegrid element of the vacuum tube, one terminal of the filament being connected with an intermediate point in the inductance.

In testimony whereof we aflix our signatures.
